Receiving the error Unparsable SDP (code 28)

Question

On incoming calls I am receiving the error Unparsable SDP (code 28)

Phone version: Zoiper5 5.3.8 for Windows 64bit

Library revision: v2.9.30

Phone revision: 5.3.8_Windows

UI revision: 1.2.17

To test I loaded Microsip Portable on the same windows machine (same number and credentials) and the incoming calls work fine. 

Tried:

STUN Server: Off and On

Enabled all available codecs

Enabled TCP

Use rport: Off and ON

Use rport media: Off and ON

I also have the Zoiper debug from the last failed incoming call.

Hi,

Do you have a support ticket number ?

If not, I suggest to open one by using the contact for on our website. This is some negotiation issue, but only the debug-log can show what it is.

Do not post it here, since it contains some private information.

No, I do not have a ticket because when I select "free" under contact it takes me to the FAQ. 

Thanks, 

James
